我只是从服务器获取标题，二进制数据和TTSStatus，但现在我得到的只是获得标题，二进制，标题，二进制和TTSStatus。当我从服务器获取头文件，二进制数据和TTSStatus时，下面的代码工作正常。

有人可以告诉我如何修改它吗？

for part in msg.walk():
        content_type = part.get_content_type()
        payload = part.get_payload()
        try:
            #if there is no reference file exist then create one based on the response 

            if content_type == "audio/x-wav" and len(payload):
                ref_filename = get_filename('pcm', output_filename + '_ref', outputfolder)
                if not os.path.exists(ref_filename):
                    with open(ref_filename, 'wb') as f_pcm:
                        f_pcm.write(payload)

                else:
                    print "[Warning] Reference PCM file is already there"

                cur_filename = get_filename('pcm', output_filename, outputfolder)
                if len(cur_filename):
                    with open(cur_filename, 'wb') as f_pcm:
                        f_pcm.write(payload)

                else:
                    print "[ERROR] Not able to create a Response PCM file \n"

                Error_Status = compare_files(ref_filename, cur_filename)

            #copy the header or the json response from the server

            elif content_type == "application/json":
                with open(get_filename('json', output_filename, outputfolder), 'w') as f_json:
                    f_json.write(payload)
        except:
            print "\n[ERROR] Can't Create Reference PCM or Response JSON files!"
            Error_Status = 1

看来你有时会为每个请求返回两个PCM块。以前第二个条目是空的。

以下内容将在每个文件的末尾添加一个段号。它基于我的原始代码，因此您需要将更改应用于完整的当前脚本：

    data = "MIME-Version: 1.0\nContent-Type: {}\n{}".format(res.getheader('content-type'), res.read())
    msg = email.message_from_string(data)
    segment = 1

    for part in msg.walk():
        content_type = part.get_content_type()
        payload = part.get_payload()

        if content_type == "audio/x-wav" and len(payload):
            pcm_filename = '{}_{}'.format(output_filename, segment)
            segment += 1

            ref_filename = get_filename('pcm', pcm_filename + '_ref', LNG)
            if not os.path.exists(ref_filename):
                with open(ref_filename, 'wb') as f_pcm:
                    f_pcm.write(payload)

            cur_filename = get_filename('pcm', pcm_filename, LNG)
            with open(cur_filename, 'wb') as f_pcm:
                f_pcm.write(payload)

            compare_files(ref_filename, cur_filename)

        elif content_type == "application/json":
            with open(get_filename('json', output_filename, LNG), 'w') as f_json:
                f_json.write(payload)

您还可以更改以下行：

output_filename = "".join([x if x.isalnum() else "_" for x in required_text[:80]]).replace('__', '_').strip('_')

这样可以从输出文件名中删除任何双下划线或尾部下划线。

或者，如果要将所有段附加在一起，可以尝试类似以下版本的内容。不幸的是，我无法重新创建多段响应，因此无法对此进行测试，以确定是否可以将各个段附加在一起并使其仍能正常播放：

    data = "MIME-Version: 1.0\nContent-Type: {}\n{}".format(res.getheader('content-type'), res.read())
    msg = email.message_from_string(data)
    wav_data = []

    for part in msg.walk():
        content_type = part.get_content_type()
        payload = part.get_payload()

        if content_type == "audio/x-wav" and len(payload):
            wav_data.append(payload)
        elif content_type == "application/json":
            with open(get_filename('json', output_filename, LNG), 'w') as f_json:
                f_json.write(payload)

    if len(wav_data):
        payload = ''.join(wav_data)

        ref_filename = get_filename('pcm', output_filename + '_ref', LNG)
        if not os.path.exists(ref_filename):
            with open(ref_filename, 'wb') as f_pcm:
                f_pcm.write(payload)

        cur_filename = get_filename('pcm', output_filename, LNG)
        with open(cur_filename, 'wb') as f_pcm:
            f_pcm.write(payload)

        compare_files(ref_filename, cur_filename)

如何使用Python处理来自服务器的响应？
